Answers:

Sam's current age = 24The mother's current age = 48

=========================================================

Explanation:

s = Sam's age right now

2s = the mother's age right now, since she is twice as old as Sam currently.

In 12 years time, Sam will be s+12 years old.

12 years ago from this current year, the mother was 2s-12 years old.

Since we're told these future and past ages line up, this means s+12 and 2s-12 are the same value

Set the expressions equal to one another and solve for s.

s+12 = 2s-12

s-2s = -12-12

-s = -24

s = 24

Sam is currently 24 years old.

His mother is currently 2s = 2*24 = 48 years old.

12 years ago, his mother was 2s-12 = 48-12 = 36 years old.

12 years from now, Sam will be s+12 = 24+12 = 36 years old.

Since we get 36 each time, this confirms we have the correct answers.

I need the value of x. 10x + 4 - 2x = 6x + 9 + 7

Answers

Answer:

x = 6

Step-by-step explanation:

Answer:

x=6

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

10x+4−2x=6x+9+7

10x+4+−2x=6x+9+7

(10x+−2x)+(4)=(6x)+(9+7)(Combine Like Terms)

8x+4=6x+16

Step 2: Subtract 6x from both sides.

8x+4−6x=6x+16−6x

2x+4=16

Step 3: Subtract 4 from both sides.

2x+4−4=16−4

2x=12

Step 4: Divide both sides by 2.

2x=12

Jacob used an empty can for a project shown below the pills the label of the king in find the area of the label what is the approximate area of the canned label?

Answers

Answer:

B: 100.53 in²

Step-by-step explanation:

From the image of the can label shown, we can see that;

Height; h = 8 inches

Diameter; d = 4 inches

Thus, radius; r = d/2 = 4/2 = 2 inches

The can is a cylinder and the label covers only the curved surface area. Thus, formula for curved surface area of a cylinder is;

A = 2πrh

Thus;

A = (2π × 2 × 8)

A = 100.53 in²
